The following is valid for the flow direction:
Valve plug close-off movement must always be
directed against the flow. This requirement is
fulfilled when the valve is installed as directed by
the symbols on valve body
Note:
When using a mixing valve it is recommended that
the main flow be used for flow control (due to equal
percent plug characteristic).
